Amash, 39, became the first Republican congressman to speak out in favor of impeaching Trump in mid-May, after the release of the Mueller report. He said the investigation of Russia’s interference into the 2016 U.S. election had found abundant evidence that Trump had obstructed justice—bucking his party and echoing the conclusions of many Democrats.

Indeed, Amash believes that other Republicans would have joined him in denouncing the president’s oppositional and unethical conduct, had they not been afraid of being singled out by their colleagues for personal, nasty attacks.
